At the initial launch, each xU308 will represent 1oz of uranium. However, with the minting of additional tokens, a xU3O8 may no longer correspond to exactly 1oz of uranium. Instead, it will represent a proportional ownership share over the pool of uranium assets held in trust. (Additional new user tokens are calculated daily, minted every business day, and held in the treasury, as per the xU3O8 smart contract fee structure).
You can see your equivalent U3O8 holding in the xU3O8 dApp platform dashboard.
